Physical vapor deposition (PVD) is widely used in manufacturing ultra-thin layers of amorphous organic solids. Here, we demonstrate that these films exhibit a sharp transition from glassy solid to liquid-like behavior with thickness below 30 nm. This persists even at temperatures well the glass temperature, T$_{\mathrm{g}}$. The enhanced dynamics can produce large scale morphological features during PVD and lead dewetting instability held as low T$_{\mathrm{g}}$-35 K. We measure effective...
Abstract Inorganic ions determination has been receiving increased attention due to its strong environmental and biomedical impact. Surface‐enhanced Raman scattering (SERS) spectroscopy considered be a promising alternative method for inorganic analysis. Initially, the detection of is indirectly achieved by monitoring SERS spectral alteration molecular probe (Raman reporter) upon interaction with specific ion. Recent years, based on incorporation functional molecule, an aptamer, nanocatalyst...
For partial discharge (PD) detection of less-oil immersed electric equipment (CT, PT, bushing), frequent sampling oil chromatographic is likely to cause negative pressure inside the equipment, and by modifying terminal tap access impedance, it will endanger reliability long-term grounding tap. Based on this, in this paper, a combined on-line monitoring method for PD based UHF proposed. used detect real-time features defect, accumulative degree insulation deterioration. An oil-immersed...
Sulfur hexafluoride (SF6) is widely used in the power industry because of its excellent insulation and arc extinguishing performance; however, as global environment deteriorating, need to replace SF6 becoming significantly critical. In recent years, C5F10O has received extensive attention a potential alternative SF6. this study, part N2 C5F10O/N2 was replaced by O2, breakdown voltages C5F10O/N2/O2 at different oxygen concentrations under slightly uneven electric field were tested. The...
In this work, we systematically investigated the effect of four bis(benzimidazole) derivatives containing different heteroatoms in molecular structures on inhibiting corrosion N80 steel 0.5 mmol·l −1 H 2 S solution by potentiodynamic polarization, electrochemical impedance spectroscopy and metallographic microscope. The results showed that within range 0.1–1.0 , adsorption surface was found to follow Langmuir isotherm. Meanwhile, stable adsorbing monolayer between inhibitors metal formed,...
CaCu 3 Ti 4 O 12 (CCTO) ceramics were synthesized by a spark plasma sintering technique, and then annealed in air at different temperatures. The characterization methods including X-ray diffraction, photoelectron spectroscopy indicated that the composition distribution, valance of ions CCTO have great dependence on annealing temperature, which result dielectric properties temperature. 500 700 °C can enhance constants greatly, loss high frequence (1 MHz) reduces with increase These...
Purpose High silicon iron-based alloys possess excellent corrosion resistance in certain specific media, but the effects of electrolysis parameters on remain unknown. This study aims to guide development and application an extra-low carbon high alloy (ECHSIA) electrode plates. Design/methodology/approach The ECHSIA a conventional high-silicon cast iron (CHSCI) was analyzed through experimental characterizations. morphology observed by scanning electron microscopy. influence investigated...
Twenty-first century as an important symbol of the era knowledge economy and big data, Internet networking have a rapid development become indispensable data sources in people's lives. Besides, because its convenience quickness, these are increasingly applied more aspects. Among them, POI true representative geographical entity on network map can be abstracted point related applications it academia very broad, but few scholars studied urban benchmark land-price. Therefore, this paper takes...
Abstract Hot dip plating is a main methods of iron and steel protection, but the traditional hot galvanizing products can not meet actual needs. The addition aluminium (Al), magnesium (Mg), rare earth (Re) other alloying elements in zinc solution has become research topic. In order to obtain multicomponent alloy coating with high corrosion resistance, new type was obtained by adding Re yttrium(Y) into Zn-Al-Mg bath. influence Y, Al Mg on resistance dipped galvanized coatings studied...
